I would choose babyhash due to the miner protection. But again, this is their first product so I don't know how it would work out.

The first question is: should you buy any asic? The answer is, if you expect a profit, you should NOT.

Jupiter is 1.0 W/Gh/s

Based on this analysis listed it looks like your ROI is greater or can be obtained "in theory" through the HashFast but not by much.  I say that only because of lower power consumption over time and the miner protection program.  The best bet is to get the gear first and then sell asap for more than what you paid.  If you can't get that then mine as fast as you can while trying to sell it if you can. 

Best option is to buy Bitcoins and hold or use them.  Other option get a cloudhashing contract and ride the wave.

Also HashFast may look good in this case but until unit one hits the ground and we can see what it does this is all theory.

Like the effort put into this analysis and for full disclosure I own BFL gear (selling it) and I am on order with HashFast (nervous about it) and I don't have KNC (don't plan to get it).
